B.A

Sorry, you cannot appear for the BHU B.A. Entrance exam right now as you are currently in class 12th. After giving 12th board exams, you can appear for the same.

Approximately, 50 seats are there.

Please mention the name of the college where you wish to apply.

I don't think so that there is any such option of choosing an additional paper. You need to follow the course structure given by the university.

Yes, you can if you have completed your graduation. It is distance/correspondence course of 1 year.

The college does not disclose the fee to everyone, so it is suggested that you directly contact the college and know the fee.

MBA is Masters in Business Administration and BBA is Bachelors in Business Administration. MBA is nothing but a detailed version of BBA. You can pursue any course of your interest for doing MBA in future but BBA would be a better option since it would build a base of what you would be taught in MBA.
